The calibrations showed that the cell volume was within acceptable limits. The test temperature was within the range 19.9 to 20.1°C. The sample cell volume was 37.9654 cm3. The expansion cell volume was 74.4377 cm3.

Relative density is calculated by dividing the density value (given by the instrument in g/mL) of the test substance by the value of the density of water at 4°C, which is unity:

Relative density: 2.1985 (Standard deviation 0.0031)
